6 Claims.

My' invention relates to an improvement in liquid fuel burners and has for one purpose to provide a burner which may be applied to portable fuel tanks of the type which are employed in conveying liquid fuel for military purposes and which are frequently called blitz tanks. Another purpose is to provide a burner which may be easily and quickly applied to such tank and may be efficiently locked in place and quickly removed. Another purpose is to provide a burner including means to supply air to the blitz tank to assist in the vaporization of the fuel therein and to assist in the conveyance of the vaporized fuel to the burner. Another purpose is to provide a combustion chamber which may be immediately applied toand thereabout an immediate connection with the tank.` Other purposes will appear from time to time in the course of the specification. Whereas I show my invention as applied to a socalled blitz tank, it will be understood that any Vsuitable and preferably portable fuel tank may be employed.

I illustrate the invention more or less diagrammatically in the` accompanying drawings, wherein:

Figure 1 is a vertical section with parts in side elevation;

Figure 2 is a Section on the line 2--2 of Figure 1;

Figure 3 isa section on the line 3 3 of Figure 1;

Figure 4 isa section on ure 1;

Figure 5 is a partial vertical section on an enlarged scaleiand Figure 6 is a side elevation on a somewhat enlarged scale of part of the structure shown in Figure 5, as seen from the line 5 6 of Figure l.

Like parts are indicated by like symbols throughout the specication and drawings.

Referring to the drawings, I generally indicates a so-called blitz tank having a carrying handle including three tubular members 2 and connecting securing abutments 3, 4 at the ends thereof. The top of the tank is more or less irregularly formed and includes a portion 5 spaced downthe line 4 4 of Figfwardly below the handle tubes 2 and an inclined portion apertured as at I and having an abutment lring 8 internally screw threaded as at 9 to receive any suitable removable screw threaded cap I0 permanently secured to the tank, for example by a chain II. The burner assembly includes avburner pot I2 having therein a plurality of primary airinlets I3 circumferentially spaced thereabout and located at various distances fromy the bottom. The pot has a bottom I 4 apertured as at I5. Secured to the pot bottom is the tubular member Mi which has a lower portion of reduced diameter I'I which extends through the sleeve 8 and terminates in a ledge I8 which abuts against the sleeve 8. Outwardly extending from one side of the pot i2 is an arm I9 which is in part cylindrically formed as at 20 to conform to the exterior of the center handle tube 2. One side of the cylindrical portion 20 is downwardly extended as at 2l and is provided with a laterally extending iange 22 to which is rotatably secured a locking member 23 shown as having a downwardly turned outer end 2A. 25 is a lug extending downwardly from the opposite side of the cylindrical portion 2Q. It is provided with a notch 26, for receiving the shank of the securing member 23. It will be understood that when the member 2l] is placed in the position in which it is shown in Figures 1 and 5 the locking member 23 may then be swung into the position in which it is shown in Figures 3 and 5, engaging the notch 25 and the bottom of the handle tube 2. This'is done when the sleeve I1 has been inserted in the position as shown in Figure 5, and the result is to lock the burner assembly firmly in position in relation to the blitz tank with the interior of the pot I2 in communication with the interior of the blitz tank. A row of secondary air inlet apertures is shown adjacent to the top of the pot I2 as at 3D. 3| is a centrally apertured flame ring. 32 is an outer skirt open at the bottom as at 33 and cut away as at 34 to permit the passage of the member I9. It may be rolled inwardly above the outer flange I2-a of the pot I 2, as at 35 and serves to center the flame ring 3l in relation to the pot. It is rolled outwardly as at 36 and inwardly again as at 31 to terminate in an upwardly extending generally cylindrical sleeve 38. 39 is a generally cylindrical stove or heat radiating member which may be.

slipped on the sleeve 38 and abuts downwardly against the outward bead 3'6. A cover cap 40 may he positioned at the top, abutting for example against a bead 4I. The cap 4I) may carry a top portion 42 which in turn carries a sleeve 43 about which any suitable flue extension 44 may be slipped. All the parts can be readily dis-associated from each other to take the entire burner down, as only a slip fit is employed.

Extending downwardly into the blitz tank is an air inlet tube 5e which is provided with a plurality of longitudinal slots 5I. The tube 5D has an outwardly extending elbow 52 at its upper end which extends outwardly through an apertule 53 ,in the passage member I6 and terminates 3 secondary airgthjrough the vapertures 30.

3 with an upper end 54 in communication with the atmosphere. It will be observed that the tube 50 is shown as extending to and resting on the bottom of the blitz tank. The longitudinal slots 5| provide air inlet spaces extending substantially from top to bottom of the blitz tank. For` strength the slots may be separated by sections 51a. B6 is an air controlling shutter provided With a sleeve 6l slidable and rotatable on a pivotV pin 62, the pivot pin being secured to a ring 'E3 ple by the screw B4. The pin 62 carries an abutment washer 65 the spring 66 being compressed between the abutment andthe face of 4the shut'- ter 63. The shutter may be-provided with an actuating handle 68 and is so formed that when at one limit of its movement it entirely closes the otherwise open end of the L 52 while at theY other end of its movement it leaves the open end 5d entirely open. It Yconstitutes the only adjustable control means `for controlling thefburner.

What I provide is in essence a generator type burner in which Vthe rate of combustion is `con'- `trolled by controlling the .rate of flow of air to the body of fuel. A

It willbe realized .that whereas'Ihave described and shown a practical and operative device, nev- Iertheless many changes kmay be made in size, shape, numberand 'disposition `or parts Without departing from the spirit of. my invention. I, therefore, Wish myv drawings and description to be taken as in a broad sense illustrative and diagrammatic. A

The use and operation of my invention are as ...followsz f I illustrate a, generator typeY burner which may advantageously be used vinconnection with containers in which liquid fuel is handled or shipped.

.In the use'of thelburner, the air for combustion is supplied to the pot through the apertures I3 anduBO. n The pot is of the so-Called hydroxylating type.

In'order to provide a supply of fuel to the pot for mixture with the air which flows through the primary apertures I3 and the secondary apertures Vil), I introducesorne air into the blitz tank and maintain 'a limited initial i combustion effective to vaporize some of the liq- 1 uidfuel. This vaporized but ,unburned liquid fuel moves upwardly through the neck I into i the interiorof the pot l 2. It is there mixed with the primary air ilowing in through the apertures i3.
